The device looked like smoke pellet

A 20-year-old man was detained at Derybasivska Street in central Odesa, where the security measures are tightened due to risk of provocations; road traffic is limited, key infrastructure objects are heavily guarded, and cell network goes haywire.

Today, the local residents commemorate the victims in the May 2 tragedy. Back then, on May 2, 2014, 46 pro-Russian activists perished and about 200 people were wounded during the clashes with pro-Ukrainian protesters in Odesa.

The law enforcers are checking the device.

Earlier today, the locals brought flowers to the site of the tragedy, the Trade Unions House at Kulykove field in Odesa, where the severest clashes took place in 2014. However, the police and the National Guard do not let anyone in; the locals argue with them and leave the flowers at their feet.
